"I didn't give the telescope to my father because I wanted to save something better and present it to my father together."
While Xuanzong and King Anxin were talking, Li Sixu, who had already entered the imperial study without being informed, turned around the screen and looked at Xuanzong with a smile while holding the big wooden box in his hand.
"Oh, do you have something better to give me?"
Xuanzong reprimanded her: "Little slippery man, he came to comfort me when he knew he was in trouble."
"I want to see what good thing you have in your hand."
Xuanzong snorted coldly: "It's not as good as giving you the telescope of Uncle Wang. My father will punish you even more for the matter of Hanyuan Palace."
"Why should I punish my son? It was Dalang Ya who had offended the public and attracted the royal brothers to attack him, but my son did nothing. Is my father willing to marry my son to Tubo?"
"Tubo is so far away. If I go to Tubo, I will never be able to return to Chang'an."
"Doesn't the father not want his children and subjects? Does the father want to give up his children and subjects?"
Li Sixu placed the wooden box she was holding on the table and pulled Xuanzong's sleeves to act coquettishly.
Don't think that Xuanzong didn't know. King Anxin looked proud when he heard that he didn't receive the telescope from Xiao Shi.
Now he could see clearly how his princess acted coquettishly with his father. Seeing King Anxin looking a little disappointed, Xuanzong was extremely satisfied.
He stopped when he was satisfied and patted Li Sixu's arm: "Okay, how old are you? You are still the same as when you were a child. You always like to act coquettishly with me."
"How can I be willing to marry you to Tubo?"
Xuanzong urged her: "Open the box quickly and show me what good things you have brought."
Li Sixu had almost whetted the appetites of his father and Uncle Wang, and then he opened the wooden box placed on the royal table. Xuanzong saw three things in the huge wooden box.
It was also a telescope that he was very familiar with, and it was also a folded map. Because the mountains, rivers and seas were looming above, he could identify them.
There was also something round and small, as big as a palm, that Xuanzong couldn't recognize.
When Li Sixu took out the thing and displayed it, Xuanzong saw clearly that the thing was like Siman's miniature, except that the spoon in the middle had been replaced by a needle.
Then, his tenth princess shook the thing, and the needle pointed back and forth, always pointing to the south position.
Xuanzong felt very strange: "Is this Si Nan?"
"Yes, this is indeed an improved version of Si Nan. When I was traveling abroad, I once saw an accomplished man who used a magnetic needle instead of a magnetic spoon to make a compass, which is easy to carry."
"My son then asked Mr. Liang to use a magnetic needle instead of a magnetic spoon, and then mark the directions around the disk to make a simple version of Sinan. Of course, my father can also call it a compass."
Li Sixu's eyes flashed and she told Xuanzong: "I saw that the Taoist priest's compass could be used for sacrifices, divination and measuring directions. I thought that this compass could be used in military and navigation."
Li Sixu places great emphasis on the words military and navigation.
Then Eunuch Yang stood aside and took out the map from the box at Xuanzong's signal.
On the clearly marked map, various ports along the coast of the Tang Dynasty, as well as coastal counties, as well as neighboring countries, large tracts of oceans and islands, were all displayed in front of Xuanzong.
This map marks the route from Quanzhou through Guangzhou, into the South China Sea, through the Strait of Malacca, to Tianzhu, then to Dashi, and finally to Persia.
Even the small countries along the coast are clearly marked.
Dashi and Tianzhu, which are adjacent to Tubo, were circled with rouge. Li Sixu specifically mentioned navigation and military affairs. The map pointed clearly. Xuanzong looked up in shock after reading it.
"That's what my father thought. I thought of a way to deal with Tubo once and for all."
Li Sixu explained to Xuanzong: "Tubo is vast and sparsely populated. The Tang Dynasty has been fighting Tubo for many years, which will only wear it out. Even if it conquers a large area of Tubo land, it will be difficult to manage it. Without heavy troops stationed, these conquered territories will still be exhausted." will be lost again."
"And if we send heavy troops to garrison, it will consume a lot of manpower and material resources, drag down the people of the entire Tang Dynasty, and affect people's livelihood."
Li Sixu asserted: "Even if Tubo is defeated in a short period of time, once they recover, they can come back. Since Tubo's plan for the peace talks is to join forces with the Tang Dynasty to deal with the Eastern Turks, then why can't the Tang Dynasty What about the countries neighboring Tubo joining forces to deal with Tubo?"
Li Sixu pointed at the map: "Father, look, this is a sea map that my son spent a lot of money to collect from Quanzhou. This map shows that in addition to the small country adjacent to Tubo, there is Tianzhu living south of Tubo." , to the west of Tubo is Dashi."
"If the Tang Dynasty could send envoys, carry national letters and edicts, and lead diplomatic missions to sail to the two major countries of Tianzhu and Dashi, and establish diplomatic alliances with them, would it be possible to contain Tubo?"
"If Tubo dares to disturb our border with the Tang Dynasty, Dashi and Tianzhu will send troops. If Tubo attacks Dashi and Tianzhu, the Tang Dynasty can also station troops at the border. If Tubo is attacked from three sides, it will definitely be exhausted. Give them a hundred courages, and they will also I will never dare to jump again."
Li Sixu continued her analysis: "The Tang Dynasty, whether it is separated from Tianzhu or Tubo, is separated by mountains and rivers, and there is no interest dispute over land and borders. With Tubo's banditry, even our Tang Dynasty dares to intrude, and it is adjacent to it. The neighboring countries on the border will definitely suffer from it. Being able to establish diplomatic relations with the Tang Dynasty will be beneficial without any harm. I believe that Tianzhu and Dashi will definitely be willing."
"Sending envoys to sea is just one of them."
"Secondly, many of Chang'an City's precious spices, ivory, gems, etc. come from coastal countries and Persia. When my father governs the world, he always pays attention to returning benefits to the people and making the people of the world rich, so the imperial treasury is not full. Previously, Master Yuwen was supporting me, and there was still some surplus, but now Master Yuwen committed a crime and was sent to Ruzhou."
Li Sixu told Xuanzong: "The reason why I want to sail is because I want to use the Tang Dynasty's envoys to do business with other countries, and bring a steady stream of wealth back to Chang'an to fill the treasury and help my father rule the prosperous Tang Dynasty." , providing a solid material foundation.”
Using diplomatic strategies to establish diplomatic relations and contain Tibet was such a fantastic idea that shocked everyone present in the Imperial Study Room.
No matter it is Eunuch Yang, Xuanzong or King Anxin, they will all be amazed.
However, at this time, Li Sixu came to a turning point and said that in addition to establishing diplomatic relations, she also had plans to do business. What was even more amazing was that she said she wanted to go sailing and go on missions to various countries.
Xuanzong was still immersed in the joy of being able to eliminate Tubo once and for all. When he heard her talk about going sailing, he categorically refused with a map.
"What are you talking about? Going sailing? I advise you, don't even think about it!"
